. either right or left hand doors; furthermore,

to provide simple and efficient means for securing a gravity latch-boltin its extended position to perform the functions of a lockingbolt, toprovide for the latch-bolt an adjustable stop constructed to form anauxiliary locking bolt, and to provide a reversible catch-plateconstructed to cooperate with the latch-bolt in either of the relativelyreversed positions of the lock-casing.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof Will beparticularly. pointed out in the appended claims.

In the drawings, Figure 1 is a side view of a lock constructed inaccordance with my invention, the removable side plate beingomitted andthe parts being shown in their locked positions. Fig. 2 is a similarview showing the latch-bolt released and retracted, the foremost tumblermember being omitted toshow the engagement of the other tumbler member:with the latch-bolt stop. Fig. 3 is a front view of the lock and thecooperating catch plate as seen in the positions which they 00- cupyjust prior to the engagement of the repressing-stud with the ear of thecatch-plate: Fig. 411 5 a perspective View of the catch-plate. Fig. 5 isa'similar View of oneof the tumbler members. Fig. 6 is a similar view ofthe latch-bolt stop.

Similar numerals of reference indicate corresponding parts in all thefigures of the d rawings.

The casing 10f thelock embodying my invention is provided with aface-plate 2, having a latch-bolt opening 3, through which projects thenose of the latch-bolt at. This latchbolt is fulcrumed upon a pin 5contiguous to the plane of the faceplate and is provided at its rear endwith a weight 6, whereby the latch-bolt is yieldingly actuated to extendits 5 5 nose beyond the faceplate for engagement with one of theopenings 7 7 of the catchplate 8. The nose of the latch-bolt is squareor flat-sided to adapt it to engage with one of said openings 7 7, inthe CEttOll-PlfttGWllGlllM-Bl the lock is used in connection with aright or a left hand door, the catch-plate being reversible, accordingto the direction in which the door swings, to cause said nose of thelatch-bolt to engage one or theother of the said openings; and in orderthat the latchbolt maybe repressed asit approaches the catch-plate, towithdraw the nose of the bolt into the casing prior to engagement withone of said openings, I provide the latch-bolt, be

tween the plane of its nose and its fulcrum, with a repressing-stud 9,which is rounded or beveled at bothsides, and also provide thecatch-plate with a lateral ear 10, which projects to one side of theline of the openings 7 7 a sufficient distance to engage therepressing-stud and throw the latch-bolt to its retracted positionbefore the nose of the latchbolt reaches the edge of the catch-plate, as

will be understood by reference to Fig. 3,

wherein the relative positions of the nose of the latch-bolt and thecatch-plate are shown when the repressing-stud is about to engage theear of the catch-plate. The repressingstud is arranged near the centerof the faceplate in order to cooperate with the ear 10 of thecatch-plate in either position of the lockcasing and catch-plate; but inpractice I prefer to arrange it sufficiently near to the fulcrum ofthelatch-bolt to cause a slight move- 0 ment of the, repressing-stud towithdraw the nose of the latch-bolt into the casing, and in theconstruction illustrated said stud is arranged slightly below thetransverse center of the face-plate, and hence I provide the catch- Themeans illustrated in the drawings for x00 manually retracting thelatch-bolt is of the ordinary construction, including a knob-spindle hub12, having an arm or cam 13 and adapted to engage a projection 14 on thelatchbolt, as will be seen by reference to Figs. 1 and 2. i

Mounted in the casing for sliding movement and adapted to be arranged inthe path of the pivotal movement of the latch-bolt is alatch-bolt stop15, provided at its rear end with a slot 16, mounted upon a guide-pin 17and having a projection 18 for arrangement in the path of a reduced arm19 on the latchbolt, whereby the adjustment of the stop is adapted toarrange said projection 18 either in or out of the path of the reducedarm 19 to lock or release the latch-bolt.

In Fig. 1 the parts are shown in their locked positions, wherein theprojection 18 is in the path of the reduced arm of the latch-bolt, fromwhich it will be seen that the latch-bolt can be retracted neithermanually nor mechanically, and in order that the stop may be secured inthis locking position I provide a tumbler which in the constructionillustrated consists of separate tumbler members 20 20, fulcrumed upon apin 21, which is rigidly fixed to the lock-casing and arranged,respectively, upon opposite sides of the plane of the sliding stop. Thetumbler members are enlarged or weighted at their free front ends todepend in front of the arm 19 of the latchbolt and between said arm andthe hub 5 of the latch-bolt, the contiguous faces of said enlarged orweighted portions of the tumblers being arranged in contact, and thedownward movement of the free ends of the tumblers is limited by thecontact of stop-ears 21 with the hub 5 of the latch-bolt. The latch-boltstop is provided with a longitudinal catch-slot 22, in which operatestuds 23, carried by the tumblers contiguous to their free ends, saidstuds projecting into the catch-slot from opposite sides of the plane ofthe stop. At the extremities of said slot are formed main seats 24 forengagement by the said studs, respectively, when the stop is in itsextended and retracted positions. I also preferably provide saidcatch-slot with false seats 25in the upper Wall of the slot, whereby ifthe tumblers are raised beyond a certain height the studs thereon engagesaid false seats, and thus prevent the movement of the stop. Thisconstruction requires the use of a special key to adjust the stop,provision being made by means of the keyhole 26 for the introduction ofa'key suitable for disengaging the tumblers from the stop, and a notch27 is formed in the lower edge of the stop for engagement by such a keyto move said stop in the desired direction.

In addition to the above-described construc tion I have deemed itdesirable, particularly in View of the fact that the reversiblecatchplate is provided with twin openings 7 7, to employ an auxiliary orlooking bolt to engage that opening in the catch-plate which is notengaged by the latch-bolt nose, and hence I have extended the adjustablestop 15 to form an auxiliary or locking-bolt nose 28, adapted to operatethrough a suitable opening 29 in the face-plate. This auxiliary opening29 occupies a position at such an interval from the opening 3 that whenthe catch-plate is reversed, as above described, in order to suit rightand left hand doors, the auxiliary locking-bolt is adapted to engage theuppermost opening of the catch-plate, the nose of the latch-boltinvariably engaging the lowermost opening of the catch-plate in eitherposition of the latter.

In my improved lockthe latch-bolt, the slidable stop-bolt, and thetumbler mechanism are all operatively combined for service, so as tolock the latch-bolt and the stop-bolt in their projected or shotpositions. The two tumblers are disposed on opposite sides of thestop-bolt, so as to have their studs 23 project into the slot 22 fromopposite sides of the stop-bolt, so as to engage with a seat at thefront or rear end of the slot 22, according as the stop-bolt isprojected or retracted, and these tumblers are arranged close to thekeyslot, so as to be engaged by the key and then released from the seatsof the stop-bolt before the key engages with the stop-bolt notch 27, inorder to retract the stop-bolt and with its arm 18 from the path of thelocking-arm 19 of the latch-bolt. The latch-bolt and the tumblers areall counterweighted to insure their retention in operative relation bygravity and without the employment of springs, and the stop-bolt andweighted portions of the tumblers are disposed in relation to thegravity latch-bolt, so as to insure the desired operation of the partswithout hindrance one from the other. Thus without adding to the numberof parts of the look I have provided a device which is reversible tosuit right and left hand doors without the readjustment of any of theinterior construction thereof and have provided a plurality ofprojecting boltnoses, both of which are locked in their extendedpositions by the same means and both of which are releasable by a singlemanipulation of the tumblers whereby the sliding stop is secured in itsoperative position.

As shown by dotted lines in Fig. 8, the upper and lower edges of thecasing of the lock are rounded to provide for fitting the mortisedportion thereof in an opening formed solely by means of an anger withoutchiseling. This materially facilitates the affixing of a lock to a door.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

I-Iaving described my invention, What I claim is- 1. The combinationwith a casing, and a gravitylatch pivotally hung therein and provided atits upper end with the locking-arm, 19, of a stop-bolt, 15, slidablyfitted in the casing and provided with the depending locking-stud, 18,and with the longitudinal slot, 22, having the notch-seats, 24, and thegravity-tumblers arranged above the latch-bolt, on opposite sides of theslidable stop-bolt, and hung or pivoted in the casing independently ofsaid stop-bolt and the latch-bolt, said tumblers having their Weightedfree ends disposed over the latch-bolt for their lugs, 21, to rest uponthe latch-bolt hub, and said tumblers also provided with studs Whichenter the slot of the stop-bolt and are adapted to enter one or theother of the notch-seats therein accordingly as said stop -bolt isprojected or retracted, substantially as described.

2. In a lock, the combination of a casing having its face-plate providedwith terminal bolt-openings 3 and 29, and an intermediate opening 11, apivotal bolt having its nose projecting through one of said openings inthe face-plate, and provided With a repressingstud 9 extending throughthe intermediate opening of the face-plate, an auxiliary bolt mountedfor sliding movement in alinement with, forterminal extension through,the other bolt-opening, and having a projecting portion 18 for movementin a direction transverse to that of a contiguous portion 19 of thepivotal bolt, and adapted to occupy a posi tion in the path of thelatter when the auxiliary bolt is extended, means for securing theauxiliary bolt in either of its adjusted positions, and a reversiblecatch-plate provided with twin spaced bolt-openings and an intermediateopening for the reception of the repressing-stud, substantially asspecified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.
